Glycolysis splits each six-carbon glucose into two three-carbon pyruvate molecules. So 206 glucose molecules yield 206 × 2 = 412 pyruvate.

The four complexes of the mitochondrial electron transport chain are named by the reaction they catalyse. Complex II is succinate dehydrogenase, the only enzyme shared between the TCA cycle and the ETC, and it feeds electrons in via FADH₂. Complex I is NADH dehydrogenase, complex III is cytochrome bc₁ and complex IV is cytochrome c oxidase.

The conversion of succinyl-CoA to succinic acid is a substrate level phosphorylation that produces GTP or ATP; no hydrogen is removed and no electron carrier is reduced, so it is not an oxidation. The other three each reduce a carrier — succinate to malate via FAD, isocitrate to α-ketoglutarate via NAD, and malate to oxaloacetate via NAD.
